Install Instructions

Steps to troubleshoot on a 120 V (not 240 V) workbench:
WARNING: ALWAYS DISCONNECT POWER MAINS FROM UNIT AND FROM
MOTOR WHEN SERVICING! VERIFY ABSENCE OF POWER WITH YOUR
METER BEFORE TOUCHING OR CONNECTING WIRES. NEVER CONNECT
OR DISCONNECT WHEN LIVE BECAUSE OF POSSIBLE ARCING!
1. Make sure the white jumper is installed (near the short connector's location.)
2. Plug in the UZPH4's connector into the power socket on the motor. The
connector's tabs are two different sizes, preventing you from inserting the
connector improperly.
3. Plug in the UZHMF's (Adapter F for the UZ-1) connector to the signal socket
on the motor. A plastic tab prevents plugging this in incorrectly.
4. Connect one (or both) of the connectors on the YELLOW wires of the UZPH4
to the Horsepower selection wires as chosen by the chart below:
a. HIGHEST HP: connect one yellow wire's terminal to the BLUE selector
wire AND the other yellow wire's terminal to the ORANGE selector wire.
b. MID HP Range: connect one yellow wire's terminal to the BLUE selector
wire. Place provided dummy terminals (for safety) on the unused wires.
c. LOW HP Range: connect one yellow wire's terminal to the ORANGE
selector wire. Place provided dummy terminals (for safety) on the
unused wires.
The motor will not operate unless you wire the HP selection wires in one of the
above schemes. Always cap unused terminals with safety (dummy) terminals.
5. Connect the UZ-1's main harness to the Adapter F's plug. Provide live 24 VAC
power to the UZ-1's alligator clip inputs. The UZ-1's blue LED will light.
6. Connect a safety ground wire to the motor: a separate wire run from a securely
attached bare metal point on the motor to a safety ground point is required.
7. Check for safety and then provide 120 VAC power to the UZPH4's Black and
White wires. This is best done with a fused power plug. (A great way of doing this
is by using Zebra's #ZD001 Fused Test Adapter Cord with Lighted 120 V Plug.)
8. If no speed is initially selected on the UZ-1, the motor will operate after a few
seconds in a very low speed circulating mode. This is normal with no speed
selected. Selecting a speed with the UZ-1 will override this mode, although the
built in ramps and delays may take 45 seconds or so for a full speed change.
9. The motor has 4 available speeds (plus the low speed circulating mode.) It
should operate in each of them. When troubleshooting, you must allow for up to a
45 second delay and ramp time when changing speeds before getting concerned.
